Fabrication and mechanical characterization of glass fibre reinforced triaxially braided composites

The aim of this research work is to study the mechanical behaviour of dry triaxially braided glass fibre sleeves and its composites experimentally and analytically. The braided glass fibre sleeves for three angles 30 degrees, 45 degrees and 60 degrees were fabricated on a modified maypole vertical braider following a regular braid architecture. Tensile, flexural, short beam shear and impact tests were performed to evaluate the mechanical properties of the composites. A numerical model was developed, which can be used to find the elastic properties and mechanical strength values of the dry braided fabric and its composites. It was observed that the tensile, flexural and interlaminar properties of 30 degrees specimens were more compared to 45 degrees and 60 degrees. The difference between the estimated and experimental values were found to be an average of 8% for tensile moduli and 24% for the tensile strength.

Automated summary

This research focuses on studying the mechanical behavior of dry triaxially braided glass fiber sleeves and their composites through experimental and analytical methods. Different braided sleeves at angles of 30 degrees, 45 degrees, and 60 degrees were tested for tensile, flexural, short beam shear, and impact properties. A numerical model was developed to predict the elastic properties and mechanical strength values, with the 30 degrees specimens showing superior performance compared to the other angles.
